Dematerialization. In economics, dematerialization refers to the absolute or relative reduction in the quantity of materials required to serve economic functions in society. In common terms, dematerialization means doing more with less. This concept is similar to ephemeralization as proposed by Buckminster Fuller. Dematerialization is the counterargument to the idea that economics is only about 'more is better.'
